Abstract: Existence and Uniqueness of Solution of an N-unit Series Repairable System with a Repairman Doing Other WorkPages 52-57Author Abdukerim HajiBilikiz YunusAbdulla Hoxu We investigate an N-unit series repairable system with a repairman doing other work. By using the method of functional analysis, especially, C0-semigroup theory and spectral theory of positive operators, we prove the well-posedness and the existence of a unique positive solution of the system.PubDate: 2014-09

Abstract: Analysis on Metamaterials Quasi Standard Transmission Line Unit Cell by Software ToolPages 45-48Author Cong WangNam-Young Ki A compact distributed metamaterials quasi standard transmission lines unit cell is proposed in this paper. It consists of interdigital capacitor and single or double spiral inductor based on microstrip transmission lines. The area of the unit cell is much reduced when compared with the conventional microstrip metamaterials transmission lines. The performance and the fundamental properties of the conventional and the proposed unit cells are verified by 3D planar electromagnetic (EM) simulation, and the electric size is calculated and compared. Transmission lines including 10 proposed unit cells and the traditional transmission lines are simulated by full 3D simulator. The forward and backward waves in the left-handed band from the simulation demonstrate the effectiveness of the proposed metamaterials transmission lines unit cell.PubDate: 2014-09
